Energy Refund per hit let you spam Virulence and Larva. Lower strength means nothing in quicker missions and very low duration let you literally spam Larva and high range help you pulls enemies to you. Efficient build lets you spam skills efficiently, high survivability make him one of the best tank in game. And the best thing here is that he is getting better with every Stack he gain.
I simply LOVE HIM for his amazing synergy between his skills. One of the best frame in game. [Nidus] is one of my favorite frames so I tested him in a lot situations. And it's viable for any configurations. Which I'll give you of course.
This is my configuration C. Attention! Build is not for long missions, it's mostly for Arenas to farm Endo with [Nekros].
Suggested arcanes are Grace & Energize.
